Grant launches dedicated Aerona3 air source heat pump website

Recognising the increasing demand for more environmentally-friendly home heating products, we have launched a brand-new website dedicated to our range of highly efficient Aerona3 air source heat pumps (ASHP).

The range, available in outputs of 6kW, 10kW and 16kW, provides both heating and hot water to the property. With an ErP rating of A++, the Aerona3 ASHP delivers a range of benefits including greater operating efficiencies at lower external temperature, larger outputs to match the type of properties encountered and reduced operational noise levels.

Our Technical Team also offers added assistance in helping those who are either completing new build projects or retrofitting select the right unit for their property with free of charge heat loss calculations. To avail of this service, email your building plans and xml files to

Grant oil boilers champion EU compliance

Thanks to advances in burner technology and our efficient boiler designs, our entire range of Vortex condensing oil boilers are fully compliant with the next phase of the European Union’s Energy-Related Products Directive. The new legislation, set to come into effect in September this year, will set maximum nitrogen oxides (NOx) emission levels that space heaters will need to meet, reducing the overall, NOx emissions produced from heating. Seeking to improve air quality via a reduction in pollution, the legislation has outlined a NOx emissions target with a maximum of 120mg/kWh.

The Grant Vortex low NOx models include utility, outdoor modules, boiler house, combi and wall hung boilers all of which incorporate this new low NOx technology. The majority of components within the burners like fuel pumps, motors and control boxes remain the same as before, delivering continuity and familiarity for installers and engineers.

This latest product development once again demonstrates how Grant boilers meet the needs of the evolving market place well in advance of new legislation and changes.

Think Boilers. Think Grant.

Win a Volkswagen Transporter Van

We are giving boiler installers throughout Ireland the opportunity to win a once in a lifetime prize – a brand new Volkswagen Transporter Van…

Think Boilers, Think Prizes, with GRANT!

We received a double boost by winning the Innovative Product of the Year title alongside the Best Marketing Campaign at the recent Pluming and Heating Awards 2016.

The VortexAir boiler, which is one of the most energy-efficient boilers on the market, was named the Innovative Product of the Year in a highly competitive category, while the campaign ‘Think Boilers, Think Grant’ was named as the Best Manufacturing campaign.

Judges comments… ” The judges acknowledge GRANT’s innovation in being the first manufacturer to come to market with this product.”

The Grant VortexAir is a revolutionary new product from our in-house design team, and is a combination of the award-winning Grant Vortex condensing oil boiler with its latest in ‘blue flame’ technology, and the A++ Aerona inverter driven heat pump. This hybrid product allows the householder to benefit from the two most cost-effective forms of fuel – oil and heat pump – to ensure that they will never be without heat. The innovative design also offers the householder the best of renewable heating technology on one side and the Grant Vortex Blue Flame boiler on the other.

We developed the product after recognising that there was a gap in the market for a renewable energy heating system with the trusted attributes of the Grant Vortex condensing oil boiler to meet the growing demand from off-gas customers, and the industry call for cleaner heating solutions. Customers can purchase the new VortexAir from this summer, through all key plumbing and heating merchants.

The effective ‘Think Boilers, Think Grant’ campaign incorporated a fully integrated advertising campaign covering print, radio, television and online adverts alongside Grant’s first ever TV advert. This has all helped to further cement Grant’s place as a market leader with home-owners.
